Should I run losetup when using openfiler for RAC ?

Grid version : 11.2.0.3
Guest OS : Oracle Enterprise Linux 6.3
Host OS : Windows 7 (64-bit )
Hypervisor : Virtual Box 4.2.6
I am planning to set up a 2-node RAC using VirtualBox.
We are going to use OpenFiler as the storage appliance. So, totally 3 VMs (2 RAC Nodes + 1 OpenFiler VM)
Once the LUNs are available , should we be running losetup command ?
losetup /dev/loop1 /disk1as mentioned in
Re: iscsi or SAN
Isn't partition creation using fdisk enough ?
If we use shared LUNs created from withing VirtualBox , should we be running losetup ?

There is insufficient information to provide you with an answer. You are going to need to test your proposed configuration. Hopefully this is just a proof-of-concept or test environment. You have to take leave of all rational thinking to try to use this in a production environment.
You could have probably tested it (installed/tore down/resinstalled) many times over while waiting for an answer.

Why would my i7 Quad-core with 20 GB RAM run slowly when using PE12 for Mac

Hi, I am evaluating the trial version of PSE 12 for Mac but it is so slow. Are there any good reasons for this as all other programs run fine.

I don't know if you can do this with the trial, but try going to editor>help>updates and running the update to 12.1. It greatly improves performance on the mac.

Mac user, PS CC 2014 latest version. When using "Save for Web" I bring my 900 x600px @72 ppi in to SFW and the output becomes 300ppi. The only way it stays at 72ppi is if I check "none" for metadata. I know to should not matter much, but I would prefer to

Is it possible to ignore "Rigid relationships between attributes cannot be changed" when using ProcessUpdate for Dimension?

As per the title is it possible to ignore "Rigid relationships between attributes cannot be changed" when using ProcessUpdate for Dimension?
We have a case where very rarely an item might have been miscategorised so the brand is manually changed. We want this dimension to be rigid to speed up ProcessUpdate.
We do a ProcessFull each night, so it will get corrected then, but during the hourly updates we would just like to ignore this error if possible?

Hello,
The rigid relationship should be defined when the members will not change over time. Here are some threads regarding rigid relationship for your reference, please see:

In the above procedure if i substitute the values with hard coded values i.e. AR_orgid = 123 & pcountry = 'Austria' then it runs faster.
Please let me know why it is so ?

When using imovie for Ipad, how can I fast forward a project to cut the length down?

When using imovie for Ipad, how can I fast forward a project to cut the length down to fit under the 15 minutes required for Youtube? My current project is 23 minutes, and need to cut it down below 15 minutes. I was hoping to speed up the video. The content would actually be better viewed in at a faster speed anyhow.

Jon,
It sounds like you did, just as you should, Save_As and Delete everything that is unwanted. If you did the Deletion from the Timeline, there should be nothing from the old Project, that should be included. A DVD is Transcoded and burned from the Timeline. If the Assets are not there, they will not included in the DVD, even if you did not Delete anything from the Project Panel.
Tell us about the Clips now on your Timeline. Also, can you check the Timeline, by hitting the \ (Backslash key), and looking near the end of the Timeline. Do you have any "orphans" out there? Check all Video Tracks, even if you have to scroll to see them all. Does the Duration of the Timeline (viewed in the Program Monitor) match what you think that it should? If not, then you most likely have orphans, that you missed Deleteing.
Good luck,
Hunt

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

HT4864 My outgoing email as stopped working when using Outlook for mac 2011. Any suggestions?

My outgoing email as stopped working when using Outlook for mac 2011. I have deleted and reinstalled the account twice. I have 11 gig free on my iCloud account. The outgoing server is set at smtp.mail.me.com using port 587. If I was able to reinstall the account, I am positive I have the correct password. I can log into my iCloud accout using the same credentials.
Any suggestions?

I called Microsoft to fix my problem...for those maybe having the same issue, I was told by the Tech to use this outgoing server setting - p06-smtp.mail.me.com
All is working fine since doing so.

Using NFS for RAC

Hi I am planning to use NFS for RAc but I am not able to find the certified NAS devices.Where can I get the list
Thanks

NAS is NFS.
See
Following NFS storage vendors are supported: EMC, Fujitsu, HP, IBM, NetApp, Pillar Data, Sun, Hitachi.
NFS file servers do not require RAC certification. The NFS file server must be supported by the system and storage vendors.
Currently, only NFS protocol version 3 (NFSv3) is supported.

Single Vertical Line When Using ADF for Scan or Copy on HP Officejet Pro 8600

HP Officejet Pro 8600 Premium Printer (CN577A)
OS: MS 7 64 bit
When using the ADF for my CN577A HP Officejet Pro 8600 Premium printer, I get a single vertical line on the document that is produced. This occurs when copying or scanning, both in black and white, and in color. If I scan or copy using the glass, I don't get the vertical line.
I already tried the troubleshooting. I unplugged the printer, left it without power for several minutes; that didn't correct the problem. Next, I cleaned the rollers and the glass; I still get the vertical line, but only when using the ADF.
My firmware version used is current (CLP1CN1150CR).
What should I check next?
This question was solved.
View Solution.

The ADF uses its own glass area on the scanner bed, it is the narrow (about 1" wide) strip on the left. Cleaning this area should resolve the issue. A single small spot would cause the issue you are seeing.

Is it possible to preset to JPEG High when using 'Save for Web...'?

Hi,
I am using photoshop elements 10. When I am ready to save an image under 'SAVE FOR WEB..' can I preset it to 'JPEG HIGH' cos right now it will pop up 'GIF'.
When I am using PSE2, I am able to launch it as JPEG HIGH. Now, I have to click on the popdown menu to select 'JPEG High'.

You need to right-click on the PSE desktop icon and choose "Run as Administrator".
Then, open a file in PSE, use Save for Web and change all the settings to what you prefer. Hold down the Alt key and the "Done" button will change to a "Remember" button. Click it and then save your image. The settings will be saved and you do not have to run PSE as an administrator again.

Question about file size when using "Export for Web"

Hi!
I created a .mov file and worked to get a great balance between file size and quality so that I could deliver it via the web and make it easier for end users to see the video on a slower connection.
My question: When I use "Export for Web," my .mov file is converted into a very large .m4v file--more than double the size of the original file. I know that this export option is to optimize the file for a wide variety of users/internet speeds. Am I correct in guessing that the end size is not an issue? I would post the .mov file instead, but I really like the option of embedding into a html page along with the "click to play" option.
Bottom line--is it better to post the smaller .mov file that i originally started with or to go ahead and link to the bigger .m4v file that was created with the "Export for Web" option?

"Export for Web" is a feature of QuickTime Pro and it makes 4 files and the html page code for easy copy/paste Web page editing.
The very first file is called a "reference movie" and it links to the other 3 files (56kbps, 900kbps and 1.5Mbps). It, and the page code, "read" the connection speed of the viewing hardware and "serve up" the correct file based on that connection speed.
In nearly all cases the "Desktop" version would still be smaller in file size than the original source. The times the file would "increase" in file size would be when an already compressed was used as the source file. You can find out more about your source file by opening it in QuickTime Player and viewing the Movie Inspector window information.
There are dozens of other html "tricks" that could be used if your source file is already compressed but you want a different display size:
Page code to show "aspect" or scale="tofit". This code allows values "outside" of those found in the actual QuickTime file be used for the Web page display. A 320X240 QuickTime .mov file looks pretty good at double size (640X480) but the file size would still be that of the source file.
"Poster Movie" is another html trick that loads the Web based file directly in the QuickTime Player application (bypassing Web page layout restrictions). These files are also known as "Presentation Movies".
Another method is the QuickTime Media Link file (.qtl). These are simple text based files that are used as a "direct link". These use simple XML (Extensible Markup Language) and are easily created in any text editing application. The simple syntax has amazing control over a simple QuickTime .mov file. You can launch (and quit) the QuickTime Player, display at other dimensions and even embed "links" inside the display.
Some of my files as examples:
http://homepage.mac.com/kkirkster/Lemon_Trees/ a "Poster Movie" style.
http://homepage.mac.com/kkirkster/.Public/RedneckTexasChristmas.qtl
A QuickTime Media Link file. A tiny file should download to the viewing machine, launch QuickTime Player, present the movie and it even includes a "link" to my Web page.
Edit: It appears you must now double click the .qtl download to launch QuickTime.
